Guntermann & Drunck GmbH

We are the leading KVM manufacturer for control room applications.

Guntermann & Drunck GmbH (G&D) is a leading KVM manufacturer for control room applications. KVM products create a rock-solid basis for a reliable, future-oriented and fail-safe IT architecture. Whether air traffic control, broadcast applications, offshore platforms, energy control rooms or industrial process control, KVM solutions from G&D are used wherever system security is of particularly high relevance.

In 1985, G&D began developing hardware that was used to support software training. Shortly after its foundation, the company in Siegen specialized in KVM (keyboard-video-mouse) products. With its core competence in extending, switching and distributing standardized computer signals, G&D has developed into the leading KVM manufacturer for control room applications. G&D KVM products are developed, manufactured, sold and serviced at the Siegen site.

The diversity of G&D devices is reflected in their countless possible applications and, thanks to the numerous combination options, they are suitable for use in a wide variety of working environments. The company offers the broadest KVM portfolio on the market. With a wide variety of transmission types and support for all common computer signals, all conceivable customer requirements can be met.

IP-based KVM systems have been gaining in importance for years. By developing its own KVM-over-IP solution, G&D has set itself apart from the competition. With additional security features, KVM installations can be protected even more effectively against risks and used in a fail-safe manner in 24/7 operation. KVM-over-IP enables flexible, reliable and extremely secure infrastructures and creates user-friendly systems that are intuitive to operate and can be easily scaled as required, allowing critical processes to be controlled securely and without disruption.
